[vtkusers] vtkMassProperties

[Ziad Rahhal]

Hi Hendrik,

I did what you told me and it is attached again, but I
am still having the same result wich is 0. But if I
connect vtkMassProperties directly to skinExtractor
(vtkContourFilter) it does works, but I guess this
should not be the solution.

Thanks again,

Ziad
